It does. Incoming and outgoing messages are synchronized across all your devices. Work on that feature began in 2012 (before Matrix was born), and is specified in XEP-0313: https://xmpp.org/extensions/xep-0313.html https://xmpp.org/extensions/xep-0313.html
Due to people having multiple devices, and those devices having unreliable connections, it's obviously an essential part of any XMPP-based IM client these days. It's been required for full XMPP IM compliance since at least 2018.
